In recent years with the advent of cloud and modern UI technology, we have decentralized and distributed the processing power, storages and applications across many geographies. The middleware which connects a user with the backend is nothing but RESTful Services. Hence lightweight REST Services have become ubiquitous across many industries. In this tutorial we will learn How to Automate REST API JSON Schema Validation testing using Postman.

As we have seen in the spider man movie, power comes with responsibilities. So the testing the REST Services has become very critical part of the development workflow/lifecycle.

We will be looking into How to connect to TitanDB using Gremlin API in this tutorial. Interacting with TitanDB is bit different than other databases, since you can only use a WebSocket or HTTP Connection. First we will discuss on the challenges and explore a future proof way of interacting with TitanDB from Spark using Scala using Gremlin API. Then we will see how to Configure TitanDB and then use Play framework to connect to TitanDB over HTTP ( RESTful way ). We also may need to submit multiple queries together. we will learn how to combine queries in different ways.

Univariate Linear Regression is probably the most simple form of Machine Learning. Understanding the theory part is very important and then using the concept in programming is also very critical.In this Univariate Linear Regression using Octave – Machine Learning Step by Step tutorial we will see how to implement this using Octave.Even if we understand something mathematically, understanding the implementation can be tedious. Since many professor/researcher uses Octave/MatLab for teaching Machine Learning, it could be very well the the first tool you might be using to understand machine learning.This tutorial will help you to get familiar with Octave/MATLAB and understand the implementation in much easier way, without spending lot of time in Octave/MATLAB.

Today we will learn How to Create Interactive Charts using D3.js. In order to make our learning close to real life problem we will use the data provided by Nasa and use that to create our Interactive Charts. We will be using GISS Surface Temperature Analysis data provided by National Aeronautics and Space Administration. You can find more details at http://data.giss.nasa.gov/gistemp.

With a rapid growth in popularity, Microservices are becoming ubiquitous in any modern application architecture. It has become important to understand the concept of Microservices and how to implement. In this How to Develop Microservices using Netflix OSS and Spring Boot tutorial series, I will try to explain the fundamentals of Microservices and implement the same using sample examples.
